DICE SET REPLACEMENT GAME FOR BACKGAMMON SET WITH DOUBLING DICE

Product Information

An optional rule in money play: If both players throw the same number on the first roll of a game, the stakes are doubled. The doubling cube is turned to 2 and stays in the middle. Players usually agree to limit the number of automatic doubles to one per game. By analogy to market loser.] A sequence of two rolls (one for you and one for your opponent) which takes a game from a position in which your opponent would refuse a double to a position in which your opponent would accept a double. A elimination event, usually with a large entry fee, in which only the winner and runner-up receive prize money. Once all your pieces have made it around the board, you may start removing pieces (also known as "bearing off"). A piece can bear off if: A rollout which is not played to the end of the game. Instead, the position is rolled out a given number of plies (the horizon of the rollout) and estimates of the equities of the resulting positions are averaged together. A truncated rollout has more systematic error than a full rollout but is faster because each trial is shorter, and a truncated rollout has less variance so fewer trials are required to converge on a result. See post by Gregg Cattanach.

A long indirect shot with few combinations (2); in particular, a roll that hits an outfield blot from the opponent's one-point. Fiske, Willard (1905).

"A Foregone Conclusion: Fore-Edge Books Are Unique Additions to Ransom Collection". The University of Texas at Austin. Archived from the original on 2006-06-21 . Retrieved 2006-08-08. A comparison of the cost of doubling slightly before opponent's drop point versus doubling slightly past opponent's drop point. This number varies depending on the score of the match, the level of the cube, and the chance of gammon in the current game. From the online match between Kit Woolsey and Readers at GammonU. When the Readers' play is obvious, they are greeted with a link that says "Next" and the game proceeds without a vote.] A move that is clearly better than the alternatives or obvious enough that it requires no explanation.

In money play with the doubling cube, the absolute value of a position to one of the players compared to the initial stake being played for. See: Equity. Cubeful equity considers the current value of the cube, cube ownership, and the potential for future doubles. In match play, cubeful equity corresponds to the probability of winning the match from the current position. Compare: Cubeless Equity. The relative standing of the players' pip counts. The player with the lower pip count is said to be ahead in the count. Team, GCT (2018-01-23). "All You Need To Know About Tavli, Greece's National Board Game". Greek City Times . Retrieved 2022-05-02. All of the cube decisions associated with a given position, namely: (a) whether the player on roll should double, and (b) whether his opponent should accept the double, refuse the double, or possibly beaver.

If the same number is rolled on both dice, the player plays as if there were four dice, all showing the same number. A container, usually made of leather, plastic, or wood, used for shaking and rolling dice. There is often a ridge around the inside of the open end designed to trip up the dice as they leave the cup. Dice cups make it possible to shake the dice thoroughly before rolling them, ensuring a random roll. Presumably dice manipulation is harder when dice are rolled from a cup. The probability of winning the current game if it is played to conclusion without a doubling cube; also called cubeless probability of winning. A tournament for players who lose in the first rounds of the consolation flight or later rounds in the main flight. An optional chouette rule which says: when only one player accepts box's initial double, that player must also beaver; otherwise, he must refuse the double along with everyone else. See post by Roland Scheicher. Compare: Mandatory Extras (1).If the opponent has not borne off any pieces, this is a "gammon" and worth double the current stake. To make a comment during the game within hearing distance of the players (undesirable behavior in a tournament). A position of known value that serves as a standard by which other similar positions may be measured or judged. See: Cube Reference Position.

The range of game winning chances which would be a proper double and a proper take if neither player could use the cube again. Proposed by Danny Kleinman.] A guideline for cube handling in pure race positions. Compute K = (D+4)*(D+4) / (S-4), where D is the player's pip count minus the opponent's count, and S is the sum of the pip counts. Kleinman says a player should make an initial double if K > 0.44, or redouble if K > 0.61, and the opponent should accept a double or redouble if K < 1.2. See post by: Øystein Johansen. In an elimination tournament, the group in which players start and compete in until they lose, and which offers the largest prize. Compare: Consolation Flight. A feature of a problem that makes it interesting enough to appear on a quiz. The mere appearance on a quiz suggests that the "obvious" play may not be the correct play. A division of a tournament designed for players too strong for the novice division and who do not wish to compete in the open division.

The objective is for players to bear off all their disc pieces from the board before their opponent can do the same. As the playing time for each individual game is short, it is often played in matches where victory is awarded to the first player to reach a certain number of points. In a chouette, the crew member who plays for the team against the box after the original captain has declined box's double and is no longer in the game.

Purposely leave a blot within range of being hit now rather than be forced to leave it later when the danger may be greater. When moving, you must always move the top piece off a triangle. As you move a piece, you may move onto a triangle that contains: To intentionally place a blot in a position where it can be hit with the idea of enticing the opponent to give up a strategic point (2). The minimum game winning chances at which it is correct for a player to accept a double; the point at which a player is equally well off accepting a double or refusing a double; a player's drop point. Compare: Raw take point. A player who, by charm or other means, persuades another player to take part in game where the other player is at a disadvantage.

The ratio of the probability of an event happening to that of its not happening, or vice versa. Usually the higher number is given first. For example, the odds of rolling double 6's are "35 to 1 against". The use of ethically dubious means to obtain an advantage in a game. This includes intentionally distracting, confusing, or generally duping an opponent. See post by Albert Steg. Koukoules, Phaidon (1948). Vyzantinon Vios kai Politismos. Vol.1. Collection de l'institut français d'Athènes. pp.200–204. Which player has the right to make the next double. At the start of the game, the cube is in the middle and either player may double. After one player accepts another's double, he owns the cube, and only that player may make the next double. A plot showing how a position's equity is distributed among each of the 6 x 6 upcoming rolls. It provides a way to visualize aspects of a position such as volatility and duplication.
